Anything could create an emotional impact, it’s especially so when we are at odds with people and things around us.
It’s not hard to notice obvious feelings such as sadness, anger, resentment, or frustration, but understand that not-so-obvious emotions are also helpful, such as pervasive sadness, annoyance, stress even hopelessness.
The hidden emotions turned out to be valuable. They help us understand the persistent feelings that we don't always notice. Because hidden, they are the clue that guides us to uncover the beliefs and thoughts that often are not in our consciousness.
